Clinical Trial Summary

The purpose of the study is the evaluation of the clinical and radiological long-term performance of the balanSys UNI fix in a multicenter routine clinical setting.

Description:

Prospective multicenter follow-up study which examines the short- to long-term post-market clinical data on the safety and performance of the balanSys UNI fix knee prosthesis. In total at least 100 participants in 3 clinics are included in this multicenter study. The primary endpoint of the study is the Knee Society Score (KSS) 2 years after surgery. The following parameters will be collected during the regular clinical and radiological follow-up: Knee Society Score, Knee and Osteoarthritis Outcome Score (KOOS), radiographic evaluation and detection of adverse events.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Knee Society Score	The primary endpoint of the study is the Knee Society Score (KSS) 2 years after surgery; The Knee Society Score consists of an objective score (0-100 points) and a score for function (0-100 points).; A higher score means a better outcome.	2 years
Secondary	Radiographic evaluation of lucent lines	The second endpoint of interest is the incidence of lucent lines measured in millimeters by means of standard X-rays.	6-12 weeks - 10 years
Secondary	Adverse Events and Complications	Documentation of complication(s): - Description of complication with the UKA; Documentation of component revision(s) (Adverse Events): Reason(s) for revision(s); Revised component(s)	6-12 weeks - 10 years
